What happens to evaporation rate when surface area increases?
Answer and explanation
Correct answer: Increases
When surface area increases, more molecules of the liquid are exposed to air at the same time. Hence, more molecules can escape from the surface and the rate of evaporation increases. Increasing surface area alone does not make evaporation decrease or stop. Exam tip: Clothes dry faster when spread out because their exposed surface area is larger.
